Specification of Letters Patent. Patnted Jung 25, 1912,

Application led August 8, 1911.

Serial No. 642,987.

To all whom t may concern Be it known that I, HENRY W. S'rn'inrnr.-Mmnn, a citizen of the United States, and a resident of Linton, in thecounty of Greene and State of Indiana, have invented a new and ImprovedMold, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved mold moreespecially designed for making concrete fence posts and like articles,and arranged to allow convenient and secure removal of the post afterbeing molded to permit immediate reusing of the mold for forming anotherpost while the first one is setting.

For the purpose mentioned, use is made opened and closed, a drying boardfor de-` tachable connectionv with the open top of the mold body, meansfor raising the mold body, and means for turning it while in a raisedposition to bring the drying board underneath with a view to support theconcrete posts on opening the sides of thefmold body. y

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding part-s in all theviews.

Figure l is a plan view of the mold part of the drying board beingbroken out; Fig. 2 is a side elevation of the same; Fig. 3 is an endview of the same and showing the parts in position after the mold bodyis filled with concrete; Fig. 4 is a like view of the same with theparts in position after the mold body is raised; Fig. 5 is a similarview of the same with the parts in position after turning the mold bodywhile in a raised position; Fig. 6 is a like view of the same showingthe sides of the mold body open and the concrete post resting on thedrying board, part of the mold body being shown in section; and Fig. 7is a cross section of the mold body and part of the suppbrting frame.

On a suitably constructed main frame A are arranged bearings B in whichis mounted to swing, a swing frame C provided with a pivoted handle Dunder the control of the operator for swinging the swing frame C from anormal, approximately horizontal position (see Fig. 3) into an uppermostposition as shown in Fig. 4. A catch E is attached to the main frame Aand isA the tension of the springs J2.

adapted to be engaged bythe handle D owing to the sidewise pivotalmovement of the latter to hold the swing frame C temporarily in itsuppermost or a raised position shown in Fig. 4.

Cn the swing frame C is journaled a shaft F carrying the mold body G,and on one end of the said shaft F is secured or formed a crank Fadapted to be taken hold of by the operator for turning the shaft F andwith it the mold body G to turn the latter upside down (see Fig. 5) atthe time the swing frame C isheld looked in an uppermost position bythehandleDengaging the catch E (see Fig. 4). The crank F is normallylocked in place on the swing frame C by a locking catch F2 fulcrumed onthe bracket C forming part of the swing frame C.

The mold body G consists of a bottom G secured to the shaft F on whichare also secured the ends or heads G2 of the mold body G. The sides G3of the mold body are hinged or pivoted at their lower endsl at G4 ontheshaft F so that the sides G3 can swing outward into an open position(see Fig. 6) or inward into a closed position as illustrated in Figs. 3,4 and 7. When in a closed position, the sides G3 abut against the outeredges of the ends Vor heads G2, and the said sides G3 are held locked ina closed position by catches H pivoted on the ends or heads G2. Thesides G3 are provided exteriorly with legs l adapted to rest on the vthetop open so that the concrete or other plastic material can be readilyfilled into the mold body G. A

Within the mold body G and adjacent the ends or heads G2 are arrangedfalse heads J provided with longitudinally and outwardly extending pinsJ mounted to slide in the heads G2 of the mold body G. Springs J2 arecoiled on the pins J and are fastened to the head G2 and J so as tonormally hold the false heads J in an outermosti position. Cn the innerfaces of the sides G3 of the mold body G are arranged beveled lugs Kadapted to engage the outer faces of the false heads J on closing thesaid sides G3 so that the false heads J are moved inwardly toward eachother against l When the sides G3 are closed, the false heads J are intheir innermost position, thus gaging the length of the postto be made.lVhen the sides G3 of the mold body G are closed and the mold body is innormal position shown in Figs. 1, 2 and 3, the concrete or other plasticmaterial is filled into the mold body and leveled off at the top andthen a drying board K, approximately of the size and shape of the opentop of the mold body, is

placed on top of the concrete material con-l tained in the mold body. Alocking cam L is then engaged at its ends with elongated slots il formedin brackets N attached to the sides G3 of the mold body, the saidlocking cam L serving to hold the drying board K in position on the topof the concrete material and the mold body G. The locking cam L isprovided at one end' with a crank arm L for turning the cam L wheneverit is desired to move the same into locking or unlocking positionrelative to" the drying board K. After the drying board K is placed inposition and locked in place by the cam L, the operator takes hold ofthe handle D and presses the same downward with a view to swing theswing frame C into an uppermost position as shown in Fig. 4, the handleD then being engaged with the catch E to lock the swing frame C in placewhen in an uppermost position. The oper-` ator now unlocks the handle Fof the shaft F by swinging the locking arm F2 out of engagement with thecrank arm F, and then the operator turns the crank arm F so as to turnthe mold body G into an upside down position as indicatedV in Fig. 5. When this has been done, the operator disengages the handle Dffrom thecatch E to allow the swing frame C to swing downward until the dryingboard K rests on top of the main frame A as illustrated in Fig. 6. Theoperator now swings the catches H out of engagementwith the sides G3 ofthe mold body G and then swings Vthe sides G3 into an open position asindicated in Fig. 6, and in doing so, the lugs K disengage the falseheads J to allow the retract-ing springs J 2 to draw the'said falseheads J outward out of engagement with the ends of the fenceI post. Theoperator now takes hold of the handle D and swings the swing frame Cupward to completely disengage the mold body G from the fence post whichnow rests on the drying board K, and the latter with the post thereon isremoved from the main frame A and set up in a suitable place to allowtheV concrete material forming the fence post to set and harden. After,this has been done, the several parts are returned to normal position,that is, the swing frame C is lowered, the mold body G is turned backinto upright position, and the crank arm F is locked in place on theswing frames C, the Sides G3 yare closed and locked in place by thecatches H to permit of refilling the mold body with another batch of.

concrete or other plastic material. rIhe above described operation isthen repeated.

From the foregoing, it will be seen that by the use of the mold, thefence post can be quickly molded, disconnected from the mold and removedfor setting and drying to allow of immediately reusing the mold forforming another fence post while the first is drying.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
